tion of the invention, such as will enable othersskillcd in the arttowhich it appertains to make and use the same.

This invention relates to a log peeling ma- .chine in which a rotatinglog is peeled or ground by means of knives, said knives being attachedto a chain and running in a longitudinal direction relative to the log.Chain, knives and log are displaccable in all directions, so that logsof varying diameter and degree of hardness can be peeled throughout theentire day without interruption.

The disadvantages common to most log peeling machines in general use areobviated in the present invention in that the machine is arranged tooperate on logs of any desired length: it can he used for large andheavy logs of any hardness by means of adjusting devices; the machinecan work an entire day by reason of suitable adjustment of the knivesand of the logs without any interruption to the movement, and the knivescan be adjusted to suit any depthof the barkv In the accompanyingdrawings the invention is exemplified in a preferred form ofenibodiinent, with modifications.

The machine is mounted on two standards, 1, 1, which are combined bymeans of two rails, 3, which are fastened to the two projections, 2. Theupper ends or heads of the standards are enlarged, and carry thebearings, tand 5, for the shafts of the chain wheels, 6 and 6 The rearhearings, 5, are

secured tightly upon the heads of the standards, 1*, whereas the fronthearing, 4, 1S arranged in longitiulinalslots in which it is movable, inorder to allow of a longitudinal displacement. For this purpose the baseplates, 7, of the bearing, 4i, are provideo ith nuts, .in which thescrew stems, 8 and 9, are placed. On the outer end, one of the stems, 8,carries the hand wheel, 10. For the simultaneous movement of both stems,chain wheels, 12 and 12", which are connected with each other by meansof a chain, 11, are provided. In this manner, by turning the handwheeL-IO, both bearings, and also, the chain wheels, 6, aresimultaneously moved in a direction longitudinally of the screw stems,whereby the knife chain which rests upon the wheels, 6, 6, is adjusted.()n the same shaft with the vertical chair-.1 wheel, 6", the toothwheel, 13, and the belt pulley, 14-, are located. The first is in gearwith the tooth wheel, 15, which is located on the shaft, 16, said shaftcarrying on its opposite side the belt pulley, 17. The bearings, 18, forthis shaft are secured upon the bearing pinto, if), and the latter uponthe connecting rail, 3. Proceeding from the former belt pulley, H, isacrossed belt, 20 (Fig. 3) which is located on the belt pulley, 21,arranged in the lowe part ofthe standard. Said pulley, 21, is mountedupon the same shaft, with a tooth or friction clutch, or hearing, 23.The shaft 22 is in part located in a bearing arm, 24, which is fastenedto the standard, and in part in the standard itself, and carries,together withthe friction clutch, 23, a chain wheel, 25, which isconncctedby means of a chain, 26, (shown in dotted'linos in Figs. 1, 5and 6) with a chain wheel, 28, carried by the shaft, 27, and whichserves for operating the shafts, 31, 32, carrying the disks, 2%)

and 30. I

The disks, 29 and 30, which on their periphery are provided with sharpteeth, carry and rotate the log or any material which is to be worked orground, as illustrated at 33. This log is lined against displacement ina longitudinal directioufland hold in place for the purpose of moreeasily IOtftllllf" the same by a friction disk, 34, which is firmlypositioned on the sta'hdard. The motion is transmitted from the chainwheel, 28, to the shafts, 31, 32, carrying the toothed disks, 29 and 30,by means of the worm, 37 and 38, carried by the "shaft, .27, and theworm wheels, 35 and 36, which are tightly connected with the shafts ofthe disks. big. 4. The friction coupling, 23, carried by thetransmission shaft, 22, and which is operated by the lever, 23, admitsof occasional adjustment or dis engagement of the movement.

and also the plates and those pmts which are carried by the seine, such,for instance, as the bracket and the driving mechanism for the tootheddisks, and the log which is held by the letter is displaced in s lateraldirection. Since the knives are mostl tangential, that is to say, theywork with eli the surface, this displacing arrangement permits of theuse of the knives over the entire sharpened edge so that together withthe adjustment of the knives, wl'iich will be later described, theperiod of effective working of the knives is very advantageouslyincreased.

The knife chain, 78, Figs. 1, 7 to 11, consists of link membersconnected by bolts, 68, in a pivotal manner, the said members carrymitedportion of in the knives, 61. Figsv 7 and 8. show two I dii ierehtmodifications of the chains, one, that shown in Fig. 7, showing sidepieces, 69, through which pass the bolts 68 secured on both sides byscrew nuts, whereas in Fig. 8 each inemoer has on both sides perforatedprojections, 7 0, throu h which the bolts, 68,

heing provided st their ends with suitsble revisions for holding thesame in place. In 0th cases, rollers, 71, are provided which rest onthebolts, 68, in order to reduce the considerable amount of friction whichis exercised by the logs upon the movement of the chain The chain inFig. 7 con, if desired, carry the peeling knives in each alternate chainmember, A.
